The committee soon established contacts with Indian revolutionaries, including
Bagha Jatin. They visited armament and explosives factories to identify war material, and met with Indian prisoners-of-war held in Germany to recruit them to the nationalist cause.
Lala Har Dayal, who had fled to Germany after his arrest in the United States, was convinced to lend his support to the committee's cause. They established contacts with the
Ghadarite movement in the United States. Dr. Dhiren Sarkar and N.S. Marathe left for Washington, D.C., on 22 September 1915 and, through the German Ambassador,
Johann von Bernstoff, established links with the Ghadar Party. The culmination of the American efforts was the
Annie Larsen arms plot.
Kabul mission The Berlin-Indian Committee (which became the
Indian Independence Committee after 1915) created an Indo-German-Turkish mission to the Indo-Iranian border to encourage the tribes to strike against British interests. At this time, the Berlin Committee was in touch with the Khairi brothers (Abdul Jabbar Khairi and Abdul Sattar Khairi) who had settled in
Istanbul at the onset of the
World War I. In 1917 they had proposed to the Kaiser a plan to lead tribes in
Kashmir and
North-West Frontier Province against British interests. Another group, led by the
Deobandi Maulana Ubaid Allah Sindhi and
Mahmud al-Hasan (principle of the
Darul Uloom Deoband), had traveled to
Kabul in October 1915 with plans to initiate a Muslim insurrection in the tribal belt of India. Ubaid Allah proposed that the
Amir of Afghanistan should declare war against Britain while Mahmud al Hasan sought German and Turkish help. Hasan proceeded to
Hijaz. Ubaid Allah, in the meantime, established friendly relations with the Amir. At Kabul, Ubaid Allah, along with some students who had preceded him to
Ottoman Turkey to join the
Caliph's "
Jihad" against Britain, decided that the pan-Islamic cause would be better served by focusing on the
Indian Freedom Movement. This group was met by the Indo-German-Turkish mission to Kabul in December 1915, headed by
Oskar von Niedermayer and including among its members
Werner Otto von Hentig, the German diplomatic representative to Kabul; and
Raja Mahendra Pratap,
Barkatullah and other prominent nationalists from the Berlin group. Known as the Niedermayer–Hentig mission, it brought members of the Indian movement to India's border, and carried messages from the Kaiser,
Enver Pasha, and
Abbas Hilmi, the displaced
Khedive of
Egypt, expressing support for Pratap's mission. They asked the Amir to move against India. The mission's immediate goal was to rally the Amir against
British India Although the Amir made no commitment to the group, they found support amongst the Amir's immediate and close political and religious advisory group, including his brother
Nasrullah Khan, his sons
Inayatullah Khan and
Amānullāh Khān, and religious leaders and tribesmen. Under pressure from the British, the Afghans withdrew their cooperation and the mission closed down. The
Niedermayer–Hentig Expedition, with associated liaisons of the German mission had a profound effect on the political and social situation in Afghanistan. It catalyzed political change that ended with the assassination of
Habibullah in 1919 and the transfer of power to
Nasrullah and, subsequently, Amānullah; the
Third Anglo-Afghan War began, which led to Afghan Independence. ==End of the Indian Independence Committee==
